This is how your skin talks to you
Freckles are often considered a cute “attribute” and can make someone stand out from the crowd. But why do some people have them and others don't? And what are freckles anyway? Experts were able to share observations about this particular scientifically based phenomenon.
Not all people develop freckles during sunny seasons. Some had them in childhood, but disappeared in adulthood. Why is this happening? Fox News Digital journalists, in a conversation with experts, tried to find out the phenomenon of freckles.
“Scientifically known as ephelides, freckles are small pigmented spots on the skin that are more noticeable in people with fair skin,” explains Danilo C. Del Campo, MD. He also notes that they are mainly caused by a combination of genetic factors and sun exposure.
The expert attributes the appearance of freckles to the fact that when the skin is exposed to the sun, it produces more melanin, the pigment responsible for skin color.< /p>
“This is a natural reaction, but also a sign that the skin is sensitive to sunlight,” emphasizes Del Campo.
According to Del Campo, the appearance of freckles is often explained by genetics. He also says that “variants in this gene can lead to lighter skin and hair, increasing the likelihood of freckles. That's why people with red or blond hair often have freckles.»
The appearance of freckles, according to Del Campo, can begin in children as young as two years old and can become more pronounced and numerous as they age, especially after exposure to the sun.
“This occurs because the skin reacts to the ultraviolet radiation from the sun by stimulating melanocytes to produce more melanin in certain areas, resulting in the formation of freckles,” the MD comments, “Although this is a natural process, it serves as a reminder of our skin’s vulnerability to sun exposure.” «
Hair color and skin tone, like freckles, are the result of a complex interaction of genetic factors, Chelsea Wagner, senior genetics consultant at BillionToOne, told Fox News Digital.
«It's important to note that freckles can affect people of all ethnic backgrounds and skin colors,» Wagner said.
A previously existing myth was that freckles increased the risk of skin diseases or skin cancer. But according to Wagner, there are many factors, both genetic and nongenetic, that influence a person's risk of developing diseases. Dr. Del Campo agrees with his colleague, noting that freckles are not a direct factor for skin cancer.
Specialists urge people to monitor themselves or loved ones for freckles, because “it is extremely important for people with freckles to carefully follow measures sun protection, such as using broad-spectrum sunscreen, wearing hats and protective clothing, and avoiding peak hours of direct sun exposure.»
«It's important to remember that while freckles are generally harmless , any changes in their size, shape or color should prompt a visit to a dermatologist,” Del Campo emphasized.
